  • Page 5: Overview

    By adding more channels onto available fibers, the Radiance CWDM System enables greater versatility for data commu- nications in ring, point-to-point, and multipoint topologies for both enterprise and metro applications.

  • Page 6: Product Features

    Product Features The Radiance CWDM System provides the following key features: • ITU G.694.2 CWDM wavelength grid with 20 nm spacing. • Support for up to 16 different channels, each carrying 1 Gbps of bandwidth.

  • Page 7: System Description

    System Description This section describes the components of the Radiance CWDM System. CWDM Components The Radiance CWDM System is comprised of three basic components. • The multiplexer/demultiplexer (mux/demux) combines four or eight different channels onto a common network fiber. Data received from the network fiber is separated back into the individual channels and returned to the local ports.

  • Page 8: Mux/Demux

    Mux/Demux The mux/demux provides four interface ports, each mapped to a different wavelength. The mux/demux combines the channels and transmits them on a single outbound (TX) fiber. Simultaneously, the mux/demux receives the same four channels from a single inbound (RX) fiber, separates them into individual wavelengths, and delivers each to the appropriate local interface.
  • Page 9 EAST Mux/Demux #1 Channels 1-8 The Radiance CWDM System supports four 4-channel mux/demux modules and one 8-channel mux/demux. The interface ports on the mux/demux connect to any Metrobility product that supports CWDM transceivers. The network port on the mux/demux connects to another mux/demux for a point-point application, or to a drop/insert or drop/pass module for other applications.

  • Page 10: Drop/Pass Module

    There are 16 drop/pass modules, each set to drop one of the 16 wavelength- specific channels supported by the Radiance CWDM System. Dropped channels interface with any Metrobility product that supports CWDM transceivers. O A D M D R O P / P A S S...

  • Page 12: Installation Guide

    Installation Guide Follow the steps outlined in this section to install and start using the Radiance CWDM System. Unpack the System Check that the following components have been included: • R4000 chassis with pre-installed CWDM/OADM module(s) • 19-inch rackmounting hardware (2 brackets, 8 screws) •...

  • Page 13: Mount The Chassis

    Consider the overall loading before installing any equipment onto the rack. Reliable grounding must be maintained in the rack system. The R4000 is intended to be con- nected to earth ground. Radiance CWDM System...

  • Page 14: Attach The Grounding Lug

    Attach the Grounding Lug On the back panel, the R4000 provides two vertical grounding points ® where a grounding lug may be installed. Use a Panduit copper, standard barrel, two-hole lug (part number LCD8-10A-L) or its equivalent. Use two 10-32 screws to fasten the lug to the chassis. Use a No.
  • Page 15 Make sure the wavelength on the module is identical to that of the connected port. On the OADM modules, channels are dropped from eastbound traffic and inserted onto the westbound traffic. Refer to Drop/Pass Module Drop/Insert Module for more information. Radiance CWDM System...
  • Page 16 Connecting to the Network Use the Network Port for backbone connectivity. The mux/demux modules have one network port, which alternatively may be connected to an expansion port (see below). The OADM modules provide two network ports for connectivity to the east and west.
